Should a wind farm be built in a particular region, or is the integrity of the landscape a more important consideration? How should the wastewater infrastructure be designed in the future? Multi-criteria decision analysis (MCDA) is a recognised tool for weighing up such environmental questions, and an important stage of the methodology is to ascertain the preferences of those involved: What is important to them when making their decision? What

Schistosomiasis is a parasitic worm infection affecting 250 million people globally. The current prevalence thresholds for preventive chemotherapy of schistosomiasis are based on the Kato-Katz method using stool samples.

From gigantic planets to tiny imagesFrom the smallest ever printed colour image and the world's largest plant seeds to the darkest matter in the infinite expanse of the universe - over the past year, ETH research has focussed on all animate and inanimate aspects of the natural world, presenting fascinating results and ingenious inventions.

Faster entanglement of distant quantum dotsEntanglement between distant quantum objects is an important ingredient for future information technologies. Researchers at the ETH have now developed a method with which such states can be created a thousand times faster than before. In many future information and telecommunication technologies, a remarkable quantum effect called entanglement will likely play an important role.

Eyes turn into skin: how inflammation can change the fate of cells21.12.15 - EPFL scientists have found that chronic inflammation can cause regenerating cells to grow into new, aberrant types; this is called metaplasia, and is a disorder linked to prolonged inflammation. The study highlights a new concept of chronic inflammation and could lead to better treatments.

A multitool for cellsCells have an infallible sense of smell that tells them which direction to grow in to move closer to the source of a scent. ETH researchers have now learned how this sense of smell works. A frequent problem faced by cells is that they are surrounded by a promising cloud of scent and must determine the direction of its source.

Scientists predict activity of human genesGenetically identical sibling cells do not always behave the same way. So far this has been attributed to random molecular reactions. Now systems biologists of the University of Zurich have discovered an overlooked consequence of the spatial separation of cells into a nucleus and a cytoplasm. Building on top of this insight they could predict with supercomputers the activity of genes in individual human cells.

Architecture of mTOR protein complex solvedIt has long been known that the protein TOR - Target of Rapamycin - controls cell growth and is involved in the development of diseases such as cancer and diabetes. Through a collaborative effort scientists from the ETH Zürich and from the Biozentrum of the University of Basel have now succeeded in revealing the unique architecture of the mammalian TOR complex 1 (mTORC1) in detail.

Spintronics, low-energy electricity take a step closer18.12.15 - EPFL scientists have discovered a new topological insulator that could be used in future electronic technologies. Topological insulators are recently discovered materials that differ from the familiar insulators and semiconductors in many ways. While topological insulators are fascinating for fundamental physics, they could one day enable electricity with less energy loss, spintronics, and perhaps even quantum computing.

Treating colon cancer with vitamin A15.12.15 - Scientists at EPFL identify the biological pathway behind the growth of colon cancer, and block it with vitamin A. A leading cause of cancer deaths worldwide, colon cancer is famously resistant to treatment. There are many reasons for this, but one has to do with a group of persisting cancer cells in the colon that cause relapses.

The tiniest color picture ever printedResearchers of ETH Zurich and ETH start-up company Scrona achieve a new world record! They have printed a color picture depicting clown fishes around their sea anemone home.

Diagnostics with birefringenceETH researchers led by Raffaele Mezzenga have developed a new diagnostic method. It is based on Birefringence, the ability of substances to change the polarisation state of light. With this method, doctors around the world can easily, rapidly and reliably detect malaria, Ebola or HIV to name only a few.

Upside-down lightning strikes11.12.15 - Upward lightning strikes initiate on the ground and head skyward. These discharges, which usually begin at the top of tall and slender structures, pose a real risk for wind turbines.

Using "big data" to fight fluThanks to "big data", researchers have identified new molecules that are instrumental in the replication of the flu virus. If these host proteins are blocked, influenza viruses are unable to multiply as effectively. The international study therefore makes a significant contribution towards the development of new treatments and flu drugs.

Playing tennis on a smart courtTechnis, an EPFL start-up, is bringing augmented reality to the tennis court. Their newly developed technology could be used for other sports in the future.

Successful launch of LISA Path-finderAfter the successful lift-off of the Vega rocket in French Guiana, the LISA Pathfinder satellite uncoupled from its booster rocket at approximately 7.00 a.m. this morning. The satellite will spend the next 9 months floating in space. There it will enable scientists to test key measurement techniques for the detection of gravitational waves, which Albert Einstein predicted about 100 years ago in his general theory of relativity.

Genes for a longer, healthier life foundOut of a 'haystack' of 40,000 genes from three different organisms, scientists at ETH Zurich and a research consortium in Jena have found genes that are involved in physical ageing. If you influence only one of these genes, the healthy lifespan of laboratory animals is extended - and possibly that of humans, too.

Making backup plans can be a self-fulfilling prophecyIs having a Plan B always a good idea? Or can these "safety nets" actually make you less likely to achieve your goals? Psychologists from the University of Zurich propose a new theoretical framework for studying the effects of backup plans. According to their model, the more effort people put into making backup plans, the more distracting and harmful those backup plans can become.
